Description

  The present invention relates to a sterilization container having a liquid sterilization function.

  Conventionally, tap water or the like distributed in homes is sterilized with ultraviolet rays and then used as drinking water. This is because even tap water may be contaminated with bacteria such as micrococcus or E. coli. In particular, in developing countries and the like, even household tap water may not be sufficiently sterilized, or bacteria may be mixed during water distribution.

  As a water sterilizer that can be used at home, a technique is known in which attenuation from the water supply is passed through a filtration filter, the flowing filtered water is irradiated with ultraviolet rays to sterilize, and the sterilized water is stored in a tank or the like. (For example, refer to Patent Document 1). A water supply port (faucet) is attached to the tank, and water can be supplied from the water supply port and used as drinking water or cooking water.

(Embodiment 1)
[Overview]
First, the outline | summary of the water supply apparatus which concerns on this Embodiment is demonstrated using FIGS. 1-3.

  FIG. 1 is a schematic perspective view of a water supply 1 according to the present embodiment. FIG. 2 is a top view of the water feeder 1 according to the present embodiment. FIG. 3 is a cross-sectional view of water dispenser 1 according to the present embodiment taken along line III-III in FIG. Moreover, in each figure, let the left-right direction of the water feeder 1 be an x-axis direction, the front-back direction is a y-axis direction, and an up-down direction is a z-axis direction.

  The water supply device 1 according to the present embodiment is an example of a sterilization container that sterilizes a liquid and stores the sterilized liquid. The water dispenser 1 provides (provides) water to the user, for example, drinking water or cooking water. Specifically, the water feeder 1 is sterilized by irradiating ultraviolet light (UV light) to water such as tap water, well water, spring water, rainwater (hereinafter referred to as “unsterilized water”). The water supply 1 provides sterilized water (hereinafter referred to as “sterilized water”) as drinking water or the like.

  As shown in FIG. 1, the water supply device 1 according to the present embodiment is a small, lightweight, portable water supply device called a so-called water jug. The water feeder 1 may be installed in a home or the like, or may be used outdoors.

  As shown in FIGS. 1 to 3, the water dispenser 1 includes a container part 10, a water faucet part 20, a lid part 30, an ultraviolet light source part 40, and an open / close sensor part 50 (see FIGS. 4 and 5A). A drive circuit unit 60, an indicator 70, a window unit 80, and a display panel 90.

  Below, the component with which the water feeder 1 which concerns on this Embodiment is provided is demonstrated in detail, referring FIGS. 1-3 suitably.

[Container]
FIG. 4 is a schematic perspective view showing the container unit 10 according to the present embodiment.

  As shown in FIG. 4, the container part 10 is a container part in which a liquid is stored. The container part 10 has the opening part 11 for injecting liquid inside. Specifically, the liquid is water such as tap water, but may be drinking water such as tea or juice. For example, unsterilized water is injected into the container portion 10 through the opening 11, and the injected unsterilized water is stored. The stored unsterilized water is irradiated with ultraviolet rays by the ultraviolet light source unit 40 shown in FIG. 3 and then supplied (discharged) to the outside through the water tap unit 20.

  As shown in FIG. 4, a hole 12 is provided on the side surface near the bottom of the container 10. A water faucet 20 is attached to the hole 12. When the water tap 20 is operated, the liquid stored in the container 10 is supplied to the outside through the hole 12.

  Although the capacity | capacitance of the container part 10 is 6L (liter)-10L, for example, it is not restricted to this. Although the shape of the container part 10 is a bottomed substantially cylindrical shape as shown in FIG. 4, it is not restricted to this. The shape of the container portion 10 may be a bottomed rectangular tube shape, or may be a shape in which the opening 11 is smaller than the bottom portion (so-called bottle shape).

  In this Embodiment, the container part 10 has a heat retention function. Specifically, the container part 10 has a double structure of an inner container and an outer container. The space between the inner container and the outer container is a decompressed space such as a vacuum. Thereby, heat conduction is suppressed between the inner container and the outer container, and the temperature of the liquid stored inside can be maintained.

  The inner surface of the container part 10 is covered with metal. Specifically, the inner container of the container unit 10 is formed using a metal material such as stainless steel or aluminum. Thereby, since the ultraviolet-ray which the ultraviolet light source part 40 emits can be reflected in the inner surface of the container part 10, a liquid can be sterilized efficiently. In addition, the outer container of the container part 10 is formed from resin materials, such as a polypropylene (PP), for example.

  In addition, the container part 10 does not need to have a heat retention function, and does not need to have a double structure. Moreover, the container part 10 may be formed using the resin material, and the inner surface may be covered with the metal material by the plating process.

  In the present embodiment, the opening 11 is closed by a lid 30 as shown in FIG. The plan view shape (top view shape) of the opening 11 is substantially circular. Thereby, the opening part 11 can be closed by the cover part 30 by rotating the cover part 30 and screwing. As shown in FIG. 4, a container-side sensor 52 (open / close sensor section 50) is provided in the vicinity of the opening 11 of the container section 10.

  The method for closing the opening 11 by the lid 30 is not limited to the screw type. For example, you may provide the recessed part or convex part which each engages with the opening part 11 and the cover part 30. FIG. For example, the opening 11 may be closed by the lid 30 by fitting the concave portion into the convex portion. In addition, if it is simply plugged, there is no need to provide a locking mechanism.

[Water faucet part]
The water tap part 20 is an example of a supply plug part for supplying the liquid stored in the container part 10. Specifically, the water tap part 20 includes an operation lever, a water supply pipe 21, and a cover member 22. The water feeder 1 is a resin member that can be irradiated with ultraviolet rays inside the container unit 10 and includes a resin member that can be replaced by a user. Each of the water supply pipe 21 and the cover member 22 is a specific example of a resin member. The cover member 22 covers the water faucet part 20 (that is, the water feed pipe 21) inside the container part 10, and shields the ultraviolet rays from the ultraviolet light source part 40 toward the water faucet part 20. For example, the cover member 22 has a cylindrical shape, and the bottom of the cover member 22 has a mesh shape or a slit shape that shields ultraviolet rays and distributes liquid. The longitudinal direction of the slit is substantially parallel to the bottom surface of the container part 10. Thereby, the cover member 22 suppresses UV deterioration of the water faucet part 20 (that is, the water supply pipe 21) inside the container part 10. The cover member 22 can be UV-degraded, but can be replaced more easily than the replacement of the faucet part 20. Further, the water faucet 20 itself is replaceable and detachable by the user. The user can remove the faucet 20 and clean it.

  The operation lever is, for example, a push-down, pull-up, or rotary lever. When the operation lever is operated, the water tap part 20 supplies water stored in the container part 10 or stops water supply.

  The faucet part 20 is attached to the side part near the bottom part of the container part 10, for example. Specifically, the water tap part 20 is connected to the hole 12 of the container part 10. The water tap part 20 is formed from resin materials, such as a polypropylene (PP), for example.

  In addition, the position where the water tap part 20 is provided is not limited to the vicinity of the bottom part of the container part 10. For example, the water tap part 20 may be provided in the upper part of the container part 10 like a hot water pot.

  Further, the cover member 22 may not be made of resin, and may be made of metal such as aluminum or stainless steel.

[Cover (Cover)]
FIG. 5A is an overview perspective view of lid 30 according to the present embodiment.

  The lid 30 is a detachable lid for closing the opening 11. In the present embodiment, as shown in FIG. 5A, an ultraviolet light source unit 40 is attached to the back surface of the lid unit 30. Inside the lid part 30, an open / close sensor part 50 (lid side sensor 51) is arranged. As shown in FIG. 3, a drive circuit unit 60 is disposed inside the lid unit 30.

  As shown in FIGS. 3 and 5A, the lid portion 30 includes a front surface portion 31, a back surface portion 32, and a metal plate 33.

  The front surface portion 31 is a portion on the front (front) surface side of the lid portion 30 and covers the opening 11 when the lid portion 30 is closed as shown in FIG. The front surface portion 31 is, for example, a flat, bottomed, substantially cylindrical housing whose back surface (lower surface) is open and whose front surface (upper surface) corresponds to the bottom. The back surface portion 32 is connected to the lower surface side of the front surface portion 31 so as to form a space for disposing the drive circuit portion 60 therein. The surface portion 31 is formed from a resin material such as polypropylene (PP), for example.

  The back surface portion 32 is a portion on the back surface side of the lid portion 30, and covers the opening 11 when the lid portion 30 is closed as shown in FIG. 3. The back surface portion 32 is, for example, a flat bottomed substantially cylindrical disk-shaped housing whose front surface (upper surface) side is open and whose back surface (lower surface) side corresponds to the bottom. In the present embodiment, the ultraviolet light source unit 40 is provided so as to penetrate the back surface (lower surface) of the back surface portion 32. The back surface portion 32 is made of a resin material such as polypropylene (PP), for example.

  The metal plate 33 is a metal member provided so as to cover the back surface (lower surface) of the lid portion 30. The metal plate 33 is made of a metal material such as stainless steel, for example. Thereby, the ultraviolet rays emitted from the ultraviolet light source unit 40 can be reflected toward the inside of the container unit 10.

  Instead of providing the metal plate 33 on the lower surface of the back surface portion 32, the back surface portion 32 itself may be formed of a metal material.

  In the present embodiment, lid portion 30 is a screw-type lid. That is, the lid 30 can block the opening 11 by rotating the lid 30 with respect to the container 10.

  The lid 30 seals the inside of the container 10 (the space in which water is stored) by closing the opening 11. In the present embodiment, the closing of the opening 30 by the lid 30 may be described as closing the lid 30.

  Specifically, “closing the lid portion 30” means that light does not leak directly from the inside of the container portion 10. That is, when the lid 30 is closed, no gap is formed between the lid 30 and the container 10, and light does not leak from the inside of the container 10 to the outside. In the present embodiment, the water feeder 1 includes a window portion 80, and a part of the light is emitted to the outside of the container portion 10 through the window portion 80. In addition, in a state where the lid 30 is closed, it is preferable that the water stored inside the container 10 does not leak outside through the opening 11.

  The “open state” of the lid 30 is a state where the lid 30 is not closed. For example, when the lid portion 30 is opened, light leaks from the inside of the container portion 10, that is, the inside of the container portion 10 is visible from the outside.

  Although not shown, the lid 30 is provided with a plug insertion port. When the plug is connected to the insertion port, power for operating the ultraviolet light source unit 40 and the indicator 70 is supplied to the drive circuit unit 60. The lid 30 may be provided with a battery instead of or in addition to the insertion port.

[Ultraviolet light source]
The ultraviolet light source unit 40 is disposed inside the container unit 10 and sterilizes the liquid by irradiating the liquid stored in the container unit 10 with ultraviolet rays. The ultraviolet rays to be irradiated are, for example, ultraviolet rays having a peak wavelength in the range of 200 nm to 400 nm. In the present embodiment, the ultraviolet light source unit 40 irradiates ultraviolet rays having a peak wavelength of 253.7 nm as an example.

  The ultraviolet light source unit 40 is attached to the back surface of the lid unit 30. Specifically, the ultraviolet light source unit 40 is provided so as to penetrate the back surface of the lid portion 30 (back surface portion 32).

  As illustrated in FIGS. 3 and 5A, the ultraviolet light source unit 40 includes a lamp 41 and a protection member 42.

  The lamp 41 emits ultraviolet rays upon receiving electric power from the outside. The lamp 41 is, for example, a mercury lamp that emits ultraviolet rays. For example, as the lamp 41, a low-pressure mercury vapor discharge lamp having a glass tube sealed with mercury vapor or the like can be used. Instead of the lamp 41, an LED (Light Emitting Diode) that emits ultraviolet light may be used. As shown in FIG. 3, the power feeding portion of the lamp 41 is provided in the back surface portion 32 and is connected to a connector (not shown) connected to the drive circuit portion 60. For example, the lamp 41 can sterilize about 8 L of water by irradiating with a power consumption of 6 W for 3 minutes. For example, 99.9% of micrococcus bacteria contained in 8 L of water could be sterilized by irradiating ultraviolet rays for 3 minutes with 6 W of power consumption.

  As shown in FIGS. 3 and 5A, the shape of the lamp 41 is a straight tube. The lamp 41 is provided, for example, so that the major axis direction of the lamp 41 is orthogonal to the back surface of the lid portion 30 (that is, parallel to the z-axis direction). Specifically, the lamp 41 is provided so as to be detachably erected in the vicinity of the center of the back surface of the lid portion 30 in plan view. The lamp 41 can be replaced by the user. For example, the two electrodes can be attached and detached in a plug-in manner, or can be attached and detached by a connector. The lamp 41 is provided along the axis of rotation when the lid 30 is opened and closed. The tip (lower end) of the lamp 41 is located near the bottom of the container part 10. For example, as shown in FIG. 3, the front end of the lamp 41 and the faucet part 20 (hole part 12) are located at substantially the same height. Thereby, it is possible to irradiate the water stored in the container part 10 with ultraviolet rays directly and substantially uniformly.

  The lamp 41 emits not only ultraviolet rays but also weak blue light. The blue light is emitted to the outside through the window portion 80. Thereby, the user of the water feeder 1 can determine whether or not the ultraviolet ray is irradiated by looking at the window 80. The light from the LED that emits ultraviolet light also appears blue.

  The protection member 42 is a cover for preventing the lamp 41 from being damaged. For example, when the lid 30 is placed on a desk or floor, the protection member 42 prevents the lamp 41 from directly contacting the desk or floor.

  The protection member 42 is provided so as to surround the lamp 41. Specifically, the protection member 42 has a three-dimensional lattice shape, and the lamp 41 is disposed inside the three-dimensional lattice. The protection member 42 is made of a metal material such as stainless steel, for example.

  Further, the protection member 42 is detachably attached to an attachment seat 33 b provided on the metal plate 33. For example, the four legs of the protection member 42 can be inserted into and removed from the four mounting seats 33b. Thus, the protection member 42 can be attached and detached by the user, and can be temporarily removed from the metal plate 33 when the lamp 41 is replaced, for example.

  The lamp 41 and the protection member 42 are immersed in the stored water when water is stored in the container unit 10. For example, when a predetermined amount of water (for example, 8 L) is stored, at least half of the lamp 41 is submerged. For this reason, it is preferable that the lamp 41 and the protection member 42 have waterproofness.

  In addition, when the ultraviolet light source part 40 irradiates an ultraviolet-ray, the water feeder 1 is normally installed and fixed on a desk or a floor. Therefore, the water stored in the container part 10 is not water (running water) but still water. Since the ultraviolet light source unit 40 irradiates still water with ultraviolet rays, it can be sufficiently sterilized in a short period of time.

  Next, a modified example of the ultraviolet light source unit 40 having the improved protection member 42 will be described. FIG. 5B is a schematic perspective view of a lid including a modification of the ultraviolet light source unit according to Embodiment 1. FIG. 5B is different from FIG. 5A in the configuration of the protection member 42. Hereinafter, different points will be mainly described. The protection member 42 in FIG. 5B includes a first member 42a, a second member 42b, and a third member 42c.

  The first member 42 a is a member that is attached to the attachment seat 33 b of the lid portion 30 and surrounds a portion of the lamp 41 on the lid portion side.

  The second member 42b is a movable member that is attached to the first member 42a by the coupling member 42j and surrounds a part of the tip portion of the lamp 41 opposite to the lid portion 30.

  The third member 42c is a movable member that is attached to the first member 42a by the coupling member 42j and surrounds the other part of the tip portion of the lamp 41 opposite to the lid portion 30.

  The second member 42b and the third member 42c are detachable from each other while being attached to the first member 42a. That is, the latch 42b1 at the tip of the second member 42b can latch the third member 42c, and the latch 42c1 at the tip of the third member 42c can latch the second member 42b.

  FIG. 5B shows a state in which the latch 42b1 and the latch 42c1 latch the third member 42c and the second member 42b. In contrast, FIG. 5C illustrates a state where the latch 42b1 and the latch 42c1 do not latch the third member 42c and the second member 42b. When the latch 42b1 and the latch 42c1 do not latch the third member 42c and the second member 42b, the lamp tip portion of the lamp 41 opposite to the lid portion 30 is exposed. Thereby, the replacement of the lamp 41 is facilitated.

[Open / close sensor section]
The open / close sensor unit 50 detects whether or not the opening 11 is blocked by the lid 30. That is, the open / close sensor unit 50 detects whether the lid 30 is in a closed state or an open state.

  As shown in FIGS. 4 and 5A, the open / close sensor unit 50 includes a lid side sensor 51 and a container side sensor 52. The lid side sensor 51 is built in the lid part 30, for example. The container side sensor 52 is built in the container part 10, for example.

  In the present embodiment, the lid side sensor 51 and the container side sensor 52 are provided so as to be close to each other when the lid portion 30 is closed. For example, the lid-side sensor 51 and the container-side sensor 52 overlap in a top view when the lid 30 is closed.

  The open / close sensor unit 50 is, for example, a magnetic sensor. The lid-side sensor 51 has, for example, a reed switch and is electrically connected to the drive circuit unit 60. The container side sensor 52 is a magnet such as a permanent magnet, for example. When the lid 30 is closed, the reed switch of the lid-side sensor 51 is turned on and current flows. The lid-side sensor 51 outputs the current to the drive circuit unit 60 as a detection signal.

  The configuration of the open / close sensor unit 50 is an example, and is not limited thereto. For example, the lid-side sensor 51 may have a coil and output a current that flows when the lid-side sensor 51 approaches the container-side sensor 52 to the drive circuit unit 60 as a detection signal.

[Drive circuit section]
The drive circuit unit 60 controls turning on and off of the ultraviolet light source unit 40. Specifically, the drive circuit unit 60 controls the timing for turning on and off the ultraviolet light source unit 40. Note that the drive circuit unit 60 may perform control to change the intensity of the ultraviolet rays emitted from the ultraviolet light source unit 40 or the period of irradiation with the ultraviolet rays.

  In the present embodiment, the drive circuit unit 60 executes a lighting enable mode in which the ultraviolet light source unit 40 can be turned on and a lighting prohibited mode in which the ultraviolet light source unit 40 is prohibited from being turned on. In the lighting enabled mode, the drive circuit unit 60 turns on the ultraviolet light source unit 40 when the power switch 91 of the display panel 90 is pressed. In the lighting prohibition mode, even if the power switch 91 is pressed, the drive circuit unit 60 does not turn on the ultraviolet light source unit 40. The drive circuit unit 60 switches between the lighting enabled mode and the lighting prohibited mode based on the detection result by the open / close sensor unit 50.

  Specifically, the drive circuit unit 60 prohibits the ultraviolet light source unit 40 from being turned on when the opening / closing sensor unit 50 does not detect that the opening 11 is blocked. That is, the drive circuit unit 60 executes the lighting prohibition mode when the lid unit 30 is opened. Specifically, supply of power to the ultraviolet light source unit 40 is prohibited. In addition, the drive circuit unit 60 executes the lighting enabled mode only when the lid unit 30 is closed. Specifically, the drive circuit unit 60 can supply power to the ultraviolet light source unit 40. In addition, when the lid 30 is opened while the ultraviolet light source unit 40 is lit, the drive circuit unit 60 turns off the ultraviolet light source unit 40 and shifts to a lighting inhibition mode.

  In the present embodiment, for example, when the power switch 91 is pressed in the lighting enabled mode, the drive circuit unit 60 is a lamp of the ultraviolet light source unit 40 for a preset period (hereinafter referred to as “set time”). 41 is turned on. The set time is, for example, 3 minutes, but is not limited to this.

  The drive circuit unit 60 also includes a display control circuit that controls the operation of the indicator 70. The display control circuit controls the lighting display of the indicator 70 according to the state of the water feeder 1. The display control circuit includes, for example, a counter circuit that counts the number of times the lamp 41 is used (number of times of lighting) and stores the counted number of times used. Further, for example, the display control circuit determines whether or not the power supplied from the outside to the drive circuit unit 60 is within a predetermined range when the external power supply and the water supply 1 are connected via a plug. To do. Specifically, the display control circuit determines whether or not the supplied power is within a range that can be used for lighting the UV lamp 41.

  6 to 8 are a perspective view, a side view, and a front view, respectively, of the drive circuit unit 60 according to the present embodiment. As illustrated in FIG. 7, the drive circuit unit 60 includes a substrate 61 and one or more circuit components 62. 3, 6, 8, etc. do not show one or more circuit components 62.

  As shown in FIG. 3, the substrate 61 is disposed inside the lid portion 30. The substrate 61 is a printed substrate (PCB substrate) in which a metal wiring such as a copper foil is patterned on one surface (solder surface). One or more circuit components 62 are electrically connected by metal wiring patterned on the substrate 61. The metal wiring is electrically connected to the lamp 41 of the ultraviolet light source unit 40 by a cable such as a lead wire.

  As shown in FIGS. 6 and 8, the substrate 61 includes a main mounting portion 61a and a sub mounting portion 61b. The main mounting portion 61a is a flat plate portion having a substantially rectangular shape in plan view in which the upper two corners are substantially arcs. Main circuit components 62 such as a microcomputer and an inverter for turning on the ultraviolet light source unit 40 are mounted on the main mounting portion 61a. The one or more circuit components 62 include a microcomputer (microcontroller or microcomputer), an inverter, a resistance element, a capacitor, an inductor, a rectifying element, and the like.

  The sub mounting portion 61b is a substantially rectangular flat plate portion provided so as to protrude upward from the upper end surface of the main mounting portion 61a. The sub mounting portion 61b includes a switch mounting portion 61c, a first LED mounting portion 61d, and a second LED mounting portion 61e that are separated by two recesses. In the present embodiment, the switch mounting portion 61c is provided between the first LED mounting portion 61d and the second LED mounting portion 61e.

  The switch mounting portion 61c is a portion where the switch element 63 is mounted. The switch element 63 is one of the circuit components 62 and is a pressing operation type switch element for starting lighting of the ultraviolet light source unit 40. As shown in FIG. 7, the switch element 63 has a main body 63a and a pressed part 63b. When the pressed portion 63b is pushed downward toward the main body 63a, the switch element 63 outputs a control signal for starting the lamp 41. Specifically, the pressed portion 63b is pushed downward in conjunction with the power switch 91 of the display panel 90 being pushed.

  In the present embodiment, as shown in FIG. 7, the switch element 63 is disposed so that the pressed portion 63 b protrudes above the upper end of the substrate 61. Thereby, it is possible to easily push down the pressed portion 63b by applying a force from above.

  The first LED mounting portion 61d is a portion where the two light emitting elements 71 and 72 are mounted. The two light emitting elements 71 and 72 are part of the indicator 70. The two light emitting elements 71 and 72 are an example of a solid light emitting element that is disposed along the upper end of the substrate 61 and emits light upward.

  The second LED mounting portion 61e is a portion where the two light emitting elements 73 and 74 are mounted. The two light emitting elements 73 and 74 are part of the indicator 70. The two light emitting elements 73 and 74 are an example of a solid state light emitting element that is disposed along the upper end of the substrate 61 and emits light upward.

  In the present embodiment, as shown in FIG. 7, the surface on which the four light emitting elements 71 to 74 are mounted is the surface opposite to the surface on which the switch element 63 is mounted. As shown in FIG. 2, the four light emitting elements 71 to 74 are arranged on a straight line in a top view.

  In the present embodiment, the substrate 61 is inclined with respect to the bottom surface of the container part 10 when the lid part 30 is attached to the container part 10. Specifically, the substrate 61 is disposed along a direction orthogonal to the bottom surface of the container unit 10 when the lid unit 30 is attached to the container unit 10.

  For example, when the water feeder 1 places the bottom surface of the container unit 10 on a horizontal plane, the substrate 61 is inclined with respect to the horizontal plane. For example, the substrate 61 is inclined at an inclination angle of 45 ° or more with respect to the horizontal plane. Thereby, even when a liquid such as water adheres to the substrate 61, the liquid flows along the inclination, so that a short circuit of the circuit due to the liquid can be suppressed.

  In the present embodiment, the substrate 61 is disposed (vertically placed) at a substantially right angle to the horizontal plane (that is, along the vertical direction). Thereby, even when the liquid enters the inside of the lid 30 from the upper surface of the lid 30, the substrate 61 is arranged vertically, and thus it is difficult to hit the substrate 61 when the liquid falls. Therefore, it is possible to suppress a short circuit of the circuit due to the liquid.

  In addition, the connection between the drive circuit unit 60 and the internal circuit of the water feeder 1 (that is, the ultraviolet light source unit 40, the open / close sensor unit 50, etc.) may be connected via a connector. Furthermore, the portion including the display panel 90 on the upper surface of the lid 30 may be a small lid that can be detached from the upper surface of the lid 30. In this way, the user can replace the drive circuit unit 60 by opening the small lid and removing the connector of the drive circuit unit 60. Further, the small lid and the drive circuit unit 60 may be integrally formed. As a result, the small lid and the drive circuit unit 60 that are integrally formed can be exchanged as a module, and the exchange work can be facilitated.

  The four light emitting elements 71 to 74 are solid light emitting elements such as LEDs that emit visible light. In the present embodiment, the light emitting element 71 and the light emitting element 73 are an example of a first light emitting element, and emit red light. The light emitting element 72 and the light emitting element 74 are an example of a second light emitting element, and emit green light.

  In the present embodiment, as shown in FIG. 6, the four light emitting elements 71 to 74 are arranged in a straight line with the switch element 63 sandwiched in the center. The two light emitting elements 71 and 72 mainly indicate information on the power source, and the two light emitting elements 73 and 74 mainly indicate information on the lamp 41.

  Note that the number and arrangement of the light emitting elements included in the indicator 70 and the respective emission wavelengths (light emission colors) are not limited to these. For example, the indicator 70 may include only two light emitting elements or may include five or more light emitting elements. Further, the four light emitting elements 71 to 74 may be arranged not in a straight line but in a matrix of 2 rows and 2 columns. The four light emitting elements 71 to 74 may have the same emission wavelength, or may have different emission wavelengths.

  The four light emitting elements 71 to 74 display a plurality of pieces of information according to combinations of lighting / lighting modes. The mode of turning on / off includes continuous lighting, blinking lighting, and extinguishing. Continuous lighting is a state in which lighting at a predetermined luminance is continuous (continuous). Blinking lighting is a state in which high luminance and low luminance (or extinction) are periodically repeated. Off is a state in which the light is not lit (luminance is 0).

  The four light emitting elements 71 to 74 are controlled by a display control circuit provided in the drive circuit unit 60. Each of the four light emitting elements 71 to 74 is individually controlled to be turned on / off by the display control circuit.

  The plurality of pieces of information displayed by the four light emitting elements 71 to 74 include sterilization information relating to the sterilization state of the liquid by the ultraviolet light source unit 40 and life information relating to the lifetime of the ultraviolet light source unit 40. In the present embodiment, the plurality of information further includes power information related to power supplied to the drive circuit unit 60 from the outside, open / close information related to the open / closed state of the opening 11 by the lid 30, and the operation of the ultraviolet light source unit 40. Contains operational information about the state.

[Display panel]
The display panel 90 is a panel (decorative plate) provided on the upper surface of the lid 30. The display panel 90 is provided so as to cover a region including the switch element 63, the indicator 70, and the window portion 80 of the drive circuit unit 60 in plan view. Specifically, the display panel 90 has openings corresponding to the light emitting elements 71 to 74 and the window part 80, and allows light from the light emitting elements 71 to 74 and the window part 80 to pass therethrough.

  The display panel 90 has a power switch 91 at a position corresponding to the switch element 63. The power switch 91 is a push button switch. When the power switch 91 is pressed, the pressed portion 63b of the switch element 63 is pressed down. Thereby, when the drive circuit unit 60 is in the lightable mode, when the power switch 91 is pressed, the ultraviolet light source unit 40 starts irradiating ultraviolet rays, and the liquid is sterilized.

(Embodiment 2)
In the first embodiment and the modification, the stationary type so-called water jug has been described as an example, but the present invention is not limited thereto. For example, the sterilization container according to the present invention can be realized as a portable mug.

  FIG. 9 is a schematic perspective view of the lidded mug 201 according to the present embodiment. FIG. 10 is a schematic perspective view showing a state in which the lid portion 230 of the lidded mug 201 according to the present embodiment is removed.

  The mug 201 is a sterilization container and is a portable container (so-called water bottle) for storing a liquid. The lid-equipped mug 201 sterilizes the liquid by irradiating the liquid with ultraviolet rays (UV light), like the water feeder 1 according to the first embodiment. As shown in FIG. 9, the lidded mug 201 includes a container part 210, a lid part 230, an ultraviolet light source part 240, a window part 280, and a display panel 290.

  The container part 210 is a bottomed cylindrical container for storing a liquid. The container part 210 has an opening 211 for injecting liquid into the internal space. An unsterilized liquid such as tap water is injected into the container part 210 through the opening 211, and the injected unsterilized liquid is stored. The stored unsterilized liquid is irradiated with ultraviolet rays by the ultraviolet light source unit 240 and then supplied (discharged) to the outside through the opening 211. That is, in the present embodiment, the opening 211 serves as both a liquid injection port and a supply port. Specifically, the opening 211 also serves as a drinking mouth.

  The capacity of the internal space of the container part 210 is, for example, 500 mL, but is not limited to this. The container part 210 is, for example, large enough to be held by one person with one hand or both hands.

  The inner surface of the container part 210 may be made of metal such as aluminum, but may be made of resin. When the inner surface of the container part 210 is made of a resin member, ultraviolet light is irradiated from the ultraviolet light source part 240 to the inner surface of the container part 210 during sterilization. In this case, the inner part including the inner surface of the container part 210 may be replaceable by the user, or the entire container part 210 may be replaced.

  The lid part 230 is a detachable lid for the container part 210 for closing the opening part 211. The lid part 230 seals the internal space of the container part 210 by closing the opening part 211. As shown in FIG. 9, an ultraviolet light source unit 240 is attached to the back surface of the lid unit 230. As shown in FIG. 10, a drive circuit unit 260 is disposed inside the lid unit 230.

  The lidded mug 201 according to the present embodiment is carried by a user and is used outdoors where it is not possible to obtain external power supply. For this reason, a battery (not shown) is provided inside the lid portion 230. The battery is, for example, a primary battery or a secondary battery.

  The ultraviolet light source unit 240 has the same configuration and function as the ultraviolet light source unit 40 according to the first embodiment. The ultraviolet light source unit 240 is miniaturized so as to fit inside the container unit 210 and to be attached to the back surface of the lid unit 230.

  The ultraviolet light source unit 240 is disposed inside the container unit 210 and sterilizes the liquid by irradiating the liquid stored in the container unit 210 with ultraviolet rays. The ultraviolet rays to be irradiated are, for example, ultraviolet rays having a peak wavelength in the range of 200 nm to 400 nm.

  The drive circuit unit 260 has the same configuration and function as the drive circuit unit 60 according to the first embodiment. The drive circuit unit 260 is smaller in size than the drive circuit unit 60 so as to be housed inside the lid unit 230. The drive circuit unit 260 supplies the ultraviolet light source unit 240 with electric power from a battery disposed inside the lid unit 230, not with electric power supplied from the outside.

  The substrate 261 of the drive circuit unit 260 is inclined with respect to the bottom surface of the container unit 210 when the lid unit 230 is attached to the container unit 210 as in the first embodiment. Specifically, the substrate 261 is arranged along a direction orthogonal to the bottom surface (for example, a horizontal plane) of the container unit 210 (so-called vertical placement).

  As shown in FIG. 10, since the upper surface of the lid 230 is a plane, the substrate 261 is orthogonal to the horizontal plane even when the lid 230 is placed upside down. For this reason, even when the lid 230 is placed upside down, the liquid that has entered the lid 230 does not easily hit the substrate 261. Thereby, a short circuit can be suppressed.

  The indicator 270 has the same configuration and function as the indicator 70 according to the first embodiment. Since the lid 230 of the lidded mug 201 has a built-in battery, battery remaining amount information may be displayed. The remaining amount information indicates, for example, information indicating that the battery is sufficiently charged (that is, irradiation with ultraviolet rays is possible) and that the remaining amount is substantially zero (that is, irradiation with ultraviolet rays is not possible). Contains information.

  In the present embodiment, indicator 270 displays life information when power switch 291 is pressed. Specifically, when the power switch 291 is pressed, the indicator 270 displays life information, then displays operation information as in the first embodiment, and then displays sterilization information. In addition, the timing which displays lifetime information is not restricted to this, For example, you may be when the cover part 230 is closed.

  The window unit 280 has the same configuration and function as the window unit 80 according to the first embodiment. The window part 280 contains the wavelength conversion material which converts an ultraviolet-ray into visible light. Thereby, when the ultraviolet ray is lit inside the container part 210, the ultraviolet ray is irradiated to the wavelength conversion material, and visible light (for example, green light) is emitted from the window part 280. That is, since the window part 280 appears to shine green, the user can confirm that the liquid is irradiated with ultraviolet rays by confirming the light emission of the window part 280.

  The display panel 290 has the same configuration and function as the display panel 90 according to the first embodiment. The display panel 290 is smaller than the display panel 90 in accordance with the size of the lid portion 230.

  As described above, the lidded mug 201 according to the present embodiment has the opening 211 for injecting liquid therein, and the container 210 for storing the liquid, and the opening 211 for closing the opening 211, A lid 230 that can be attached to and detached from the container 210, an ultraviolet light source 240 that sterilizes the liquid by irradiating the liquid stored in the container 210 with ultraviolet light, and an ultraviolet light source 240 A resin member that can be irradiated with ultraviolet rays, and can be replaced by a user.

  Here, the opening 211 may also serve as a drinking mouth.

  Here, the resin member may be an inner part including the inner surface of the container part 210 or the container part 210 itself.

Thereby, similarly to Embodiment 1, the same effect as the water feeder 1 according to Embodiment 1 can be obtained. That is, even if UV deterioration occurs in the resin member, the sterilization container can be replaced by replacing the resin member. Can extend the service life,
(Other)
As described above, the sterilization container according to the present invention has been described based on the above embodiment and the modifications thereof, but the present invention is not limited to the above embodiment.

  For example, in the above embodiment, the example in which the cover member 82 includes the transmission part 82b and the wavelength conversion part 82a has been described. For example, the wavelength conversion material may be dispersed throughout the cover member 82. That is, the entire cover member 82 may be the wavelength conversion unit 82a.

  In this case, since the blue light from the inside does not pass through the cover member 82, it is difficult to directly check the inside. However, since the entire cover member 82 emits light during the period when the ultraviolet light source unit 40 is lit, brighter light emission can be obtained, and the irradiation state of the ultraviolet light can be more easily confirmed.

  Moreover, for example, the water feeder 1 according to the above embodiment may include a speaker. The user may be notified of the opening / closing of the lid 30, the pressing of the power switch, the start and end of the irradiation of ultraviolet rays, etc. with a dial tone from a speaker.

  Moreover, for example, the water supply device 1 according to the above embodiment may be provided with a handle portion fixed to the container portion 10 or the lid portion 30. Thereby, the water feeder 1 can be carried around easily.
